What causes oedema in severe acute malnutrition?
7.4. All severely malnourished children have deficiencies of potassium and magnesium, which may take about 2 weeks to correct. Oedema is partly a result of potassium deficiency and sodium retention.
How does protein deficiency cause edema?
Proteins in the blood tend to pull water into our blood vessels (acting like a “water magnet”). When the level of protein in the blood is low, water may leave the blood vessels and collect in the tissues. Water in the tissues is called “edema”. Critically ill patients develop edema for many reasons.
What’s the difference between pitting and Nonpitting edema?
Pitting edema responds to pressure, be it from a finger or a hand, while pitting edema does not. If you press on your skin with your finger and it leaves an indentation, you could be suffering from pitting edema. Non-pitting edema, on the other hand, does not respond to pressure or cause any sort of indentation.
What is Nonpitting edema?
Non-pitting edema refers to the accumulation of excess fluid in soft tissues, causing swelling. Although it can affect any part of the body, non-pitting edema is usually localized to certain body parts, such as the lower or upper limbs.
